Patented Au 27, 1935 BURNER Joseph C. Williams, Kansas City, Mo. A Application August 29, 1932, Serial e ligence 3 Claims. v(o1. 158 -73) 7 i This invention relates to oil burner systems used in heating plants of different types, and has for its primary object the provision of such'a system wherein is incorporated unique members and parts, all of which combine to create a'more efi'icient, effective and novel heating plant.

A further object of the invention is to provide,

in an oil burner system, means 'for automatically controlling the supply ofwater and gas or other substances through the medium of the expansibilty of a portion of the conduits built into the system.

A still further object of the instant invention is the provision of unique, novel, and improved steamgenerating and burner-head members, each of which forms an important part of the system and is created to present-exceptionally efli'cient, strong and durable parts for a system employing steam oil and air as a fuel medium.

An additional aim of this invention is to provide a burner-head having means for deflecting and guiding the flame back uponitself to a point Where it reaches the original point of exit from the tubular portion of the burner-head.

These and many more important objects will be referred to in the accompanying drawings,

wherein: a 1 f 7 Figure 1 is a broken, side elevation of a hot air heating plant having an oil burner system therein embodying the features of this invention.

Fig. 2 is an enlarged, vertical, central section through the burner-head'of the system.

Fig. 3 is a fragmentary, verticalsection of the burner-head taken on line lIIIII of Fig. 2.

Fig. 4 is a vertical, central section through the steam generator employed in the system.

Fig. 5 is a vertical, longitudinal section through the expansible length of conduit used in actuating certain valves.

Fig. 6 is an enlarged, detailed, plan view of the nozzle forming a part of the burner head, and,

Fig. 7 is a vertical, central section through the nozzle, taken on line VIIVII of Fig. 6.

The parts of the burner system contemplated by this invention might be used in any type of heating plant, and in the instance illustrated,

the same is installed in an ordinary hot air furnace ill having the customary fire box 12 that is reached through the entrance l4 thereto.

Steam is used in atomizing the supply of oil to the hereinafter described burner-head, and when this system is put into use, the hollow, spherical body iii of the steam generator I8 is supplied with water from the service mains to pipe 28 which leads to a suitable filter 22, from whence it travels tovalve '24 through the pipe 28 having a pressure reducing'valve'28 therein," and further having in communication therewith a compensating tank 38 to maintain a substantially uniform pressure, fromthis point water passes to body l6 through pipe 32. Valve 24 is always slightly open and whenstarting' the system, manually operable valve 36, interposed in pipe 32, is opened to allow water topass into body 16. A burner 3%,positioned'belowbody I6, is supplied with gas through pipe 38" and the water first introduced to body i5 is converted to steam. Pipe 33 hasa valve 49 therein which must be opened when lighting burner '35 because the ther mostatically controlled valve 52 in this pipe is. always slightly open. Gehera'ton l3- is novelly constructed. as illustrated in Fig. 4, to the extent that pipe 32 extends thereinto and is circumscribed by burner z'lE'which is held in spacedrela tion to pipe 32 by connections 46 that combine to create 'a clean-gout passage for body l6. 7 These connectionsfit'leadto-a point where a receptacle maybe placed thereunder and when PATENT ems I valve it is openedthe contentsi of body l6 willf fiowtherefrom and the interior of the body may be flushed as much as desired, and under a head of steam if needed. Y 1

After burner 35 has been lighted and water supplied to generator w s mentioned, steam is oreatedwhich escapes through pipe 48 leading to a point exteriorly' of furnace iii. This'pipe 48 joinsconnectio'n 50 which is anchored by fixture 52 to a part of furnace ill, 1 Apressure gaugeg5 4" is mounted on connection 5ii'to indicate the 3 be moved from fixture 52. When the length 56 contracts as a result of a lesser amount or no steam passing through link 55, elbow 60 will move back toward fixture 52. As steam expands length 56, valve 24 will be opened to allow theentrance of additional water to the generator. Also, as pipe 56 expands, valve .452, which supplies gas to burner 35, will be closedand when the system is under way, length 55 will be expanded to its maximum capacity; valve 42 will be closed, and

heat' for generator l8 will be supplied thereto by burner-head 66. v i

As soon as suificient steam is generated, valve 58 in oil conduit 10 will be opened topermit the passage of the fuel oil to atomizer 12, disposed atthe lower portion of the burner-head 66. The oil and steam are thrown together immediately above atomizer l2'in;a unique fashion because of the formation of atomizer 72, air being introduced' into the mixture at intake 96 just prior to ignition. f

As shown in Figs. '6 and 7, thisatomizer has a vertical, centrally disposed oil outlet port 14 which extends through nipple and member 1'8 which is in connection with pipe 10. from pipe 58 enters atomizer 18 below nipple 76 and is expelled upwardly through exit ducts 80 formed through nipple 16, as illustrated in Fig. 7.. These exit ducts converge as the-upper outlet.

end is approached. Lines projecting longitudinally from these ducts will intersect the projected vertical, longitudinal line of port 14 at a point izer.'l2 and within the fire box proper of furnace ID. The remaining portion of the burner-head 'should be positioned as illustrated in Fig. 1.

The tubular exit passage has an arch 88 formed thereover to present arcuate deflecting faces 98 which extendfrom the'upper portion of arch 88 to a point where it joins the tubular portion of the head which forms exit passage 82. A depending, transverse ridge 92 extends across arch 88 and presents its edge 94 .on thelongitudinal center line of passage 82. Thus, when flames pass upwardly into arch 88 they are divided and sent back toward the ignition point which is just below the upper edge of exit passage 82. In this manner the force of the combustion itself causes flames created thereby to positively assure ignition immediately after atomization and mixing with the proper amount of airat intake 96',

As shown in Fig. 2, there are two identically formed arcuate faces 90, one'on each side of ridge 92, and while flames are directedvback toward exit passage 82 on two sides thereof, they are permitted toescapefrom beneath arch 88 at the two opposite sidesf The overflow basin 98 is positioned below atomizer: 12 and the usual drain pipe I00 leads therefrom. to any suitable automatic cutoff, not here shown 3 v Specific structures of the various parts of this system have been made clear during the speci- Steam 7 f fication and the mode of operation and novel features have been set forth as description took place. It is understood that such modifications as fall within the scope of the appended claims and spirit of the invention might be practiced without departing therefrom.
